or a reliable function

the emitting and receiving unit must be installed
in the same polarisation direction

or this you can
use a metal plate or an angled antenna extension on the side of the

I
n products with low dielectric value

we recommend
using an instrument version with antenna extension because it
focusses the signal optimally and has no signal loss
